In a now classic experiment, Simons and Levin (1998) had a research assistant ask a pedestrian for directions. During their conversation, two people carrying a door rudely walked between the assistant and the pedestrian. However, this was part of the experiment. While the door passed in front of the research assistant, another person took his place and continued the interaction after the door passed. Half of the pedestrians didn't even notice that it was not the same person asking for directions after the door had passed by. This phenomenon is known as:
A) attention deficit.
B) change blindness.
